A meniscal tear is a tear in the meniscus. The meniscus is cartilage, which acts as a shock-absorbing structure in the knee. There are 2 menisci in each knee, a medial one on the inside, and a lateral one on the outside.

There are different types of tears depending on the location and how they look. Treatment depends on the severity of the tear.

Most injuries to the meniscus are caused by trauma. This usually includes compression and twisting of the knee. Because the aging process tends to break down the inner tissues of the meniscus, minor trauma can injure the meniscus in an older adult.
